One San Diego-area school district opted to cancel some classes Monday because of unusually high temperatures.

Coronado Unified School District Superintendent Karl Mueller decided to make Monday a minimum day due to the heat.

"I think it's a wonderful decision," said mother Dawn Bower. "The kids will be uncomfortable and it won't create a learning environment that's a good condition for them."

There are fans and film on windows of some schools to block the heat from the sun but with temperatures in the 90s expected, the district decided to send students home early.

Coronado Middle School Principal Karin Mellina agreed with the decision.

"The kids really do an awesome job. They push on through and so do the teachers," Mellina said. "But it's nice that they're able to leave by 12:30, before it gets really too hot."

The superintendent can make determination “based upon the knowledge that many of the CUSD classrooms are not air-conditioned and occasionally suffer from extreme and unhealthy temperatures,” the district said in a written release.
